SHIPPER-LOCK FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 737,864, dated September 1, 1903.

Application filed December 26,1902. Serial No. 136,545.

To all whom, it may concern:

Be it known that we, HENRY A. OWEN and OSCAR L. OWEN, citizens of the United States, residing at Whitinsville, in the county of -Vorcester and State of Massachusetts, have invented a new and useful Improvement in Shipper-Locks for Spinning-Fm mes, of which the following is a specification.

This invention has reference to spinningframes, and more particularly to mechanism for locking the shipper when access is required to the twist and builder motion gearings located in the closed box end of the frame. When a change in either the draft or twistis :5 required, the machine is stopped by throwing the belt onto the loose pulley by the shipper,-

and the change is effected by the operator removing a panel in the closed box end of the frame, giving him access to the gearing. In changing or oiling the gearing the operator has heretofore been in great danger from the starting up of the machine by the moving of the shipper by accident or other means.

The object of this invention is to lock the shipper with the belt on the loose pulley by the automatic action of mechanism connecting the shipper with the panels acting to lock the shipper when a panel is removed.

The invention consists in the peculiar and novel construction of the mechanism in connection with the panels for locking the shipper, as will be more fully described hereinafter and pointed out in the claims.

Figure l is an end view of part of a spin- 5 hing-frame, showing the driving shaft and pulleys, the belt-shipper, the removable pan els, and the mechanism connecting the shipper with the panels for locking the shipper when a panel is removed, shown in broken 0 lines. Fig. 2 is a cross-sectional view through Fig. 1, showing the driving-shaft with the fast and loose pulleys, the belt-shipper, and the shipper-locking mechanism secured to the inside of the end frame. Fig. 3 is an enlarged 5 detail view of the shipper-lockin g mechanism, showing the shipper-bar in section. Fig. l is a top view of the yoke pivoted to the shipperlocking lever and shaped to bring the lever into engagement with the two panels in the (N0 model.)

frame. Fig. 5 is a detail view showing part of the shipper-bar with the locking-teeth and the lower end of the locking-bar in section. Fig. 6 is a cross-sectional View similar to Fig. 2, slightly modified, showing the position of the shipperlocking mechanism when the shipper is used above the driving-pulleys.

In the drawings, a is the closed box end of a spinning-frame, having the two removable panels a a removably secured to the frame a in the usual way. On the back of-the frame a is secured the bearing 1), supporting the driving-shaft 12, carrying the cylinder b the fast pulley b and the loose pulley 11 The bearing 0 for the shipper c is secured on the inside of the box-frame (t. The square shipper-bar c, with the shipper c on its outer end in a position to control the belt on the pulleys, slides in the bearing 0 and has the teeth 0 to engage with the locking-bar. The shipper-bar and shipper are operated in the usual way to throw the belt onto the fast or loose pulley.

The locking mechanism is secured on the inside of the frame a and consists of a plate d, secured to the frame a and having the two bearings d d, supporting the rock-shaft d Forming a part of the rock-shaft is the locking-lever (i having the yoke 01 with the bent ends 01 d pivoted on its end by the screw d and in contact with the panels a Co. The short outwardly-extending arm 01 on the rock-shaft pivotally supports the locking-bar (i having the enlarged end (1 with the opening (1 for the shipper-bar c, the upper edge d of the opening engaging with teeth 0 on the shipper-bar c to lock the shipper by the outward movement of-the locking-lever 61 when a panel is removed.

When the gearing in the box end frame 01, requires oiling or changing, the operator stops the frame by moving the shipper-bar c and shipper c outward to throw the belt from the fast onto the loose pulley in the usual way. A panel a is now removed, allowing thelocking-lever 61 in engagement with the panel, to move outward and the locking-bar (1 downward by gravity, bringing the upper edge cl of the opening d in the lockingbar (1 into engagement with a tooth c on the shipperbar 0, locking the shipper. When the panel is replaced, it comes in contact with the yoke (l on the locking-lever d forcing the lever backward and raising the locking-bar d by the upward movement of the arm d on the rock-shaft, unlocking the shipper-bar c. The belt can now be thrown onto the fast pulley and the frame started in the usual way.

By the use of our automatic shipper-lock the frame cannot be started when a panel is removed, thus eliminating all danger to the operator from the shipper being moved by accident or other causes.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a machine having a frame .With a removable panel, a belt-shipper, and mechanism intermediate the panel and the shipper to automatically lock the shipper when a panel is removed from the frame, for the purpose as described.

2. In a spinning-machine having an end frame with removable panels, a belt-shipper, and mechanism intermediate the panels and the shipper to lock the shipper when a panel is removed or opened, for the purpose as described.

3. In a spinning-machine having a box end frame with removable panels, a belt-shipper, and mechanism secured to the end frame intermediate the panels and the shipper to automatically operate by gravity when a panel is removed to lock the shipper, for the purpose as described.

4. In a spinning-machine having a box end frame with removable panels, a belt-shipper bar, and mechanism secured to the end frame connecting the panels with the shipper-bar to automatically lock the shipper-bar when a panel is removed, and to unlock the bar when the panel is replaced, for the purpose as described.

5. In a spinning-machine having a box end frame for the gearing, removable panels in the frame, a driving-shaft with fast and loose pulleys, a belt-shipper bar with locking-teeth, and locking mechanism consisting of a plate secured to the frame intermediate the panels and the shipper-bar and having bearings for a rook-shaft, a locking-lever on the rock-shaft having a yoke with bent ends in contact with the panels pivoted to the locking-lever, and an outwardly-extending arm on. the rock:

shaft pivotally supporting a locking-bar in a position to automatically engage with the teeth on the shipper-bar to lock the bar when a panel is removed and to unlock the bar when the panel is replaced, as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
